Abstract
Load-bearing apparatus, such as a boom lift, including first and second arm portions, in which at least one element, such as a hydraulic cylinder, is provided for selectively imparting a predetermined dependent relationship as well as a predetermined independent relationship between the first and second arm portions. The manufacture of such load-bearing apparatus can be customized by preselecting the dependent and independent relationships by altering given parameters.
